6.2.1 Syntax

These are the three options for writing a binding using the `bind` node

- Long

The most complete of all three, you must specify both ends of the binding explicitly. The following snippet sets an unidirectional binding from `bean1.prop1` to `bean2.prop2`

    bind(source: bean1, sourceProperty: 'prop1',
         target: bean2, targetProperty: 'prop2')

- Contextual

This type of binding can assume either the sources or the targets depending on the context. The following snippets set an unidirectional binding from `bean1.prop1` to `bean2.prop2`

- Implicit source

    bean(bean1, prop1: bind(target: bean2, targetProperty: 'prop2'))

- Implicit target

    bean(bean2, prop2: bind(source: bean1, sourceProperty: 'prop1'))

When used in this way, either `sourceProperty:` or `targetProperty:` can be omitted; the bind node's value will become the property name, in other words

    bean(bean1, prop1: bind('prop2', target: bean2))

- Short

This type of binding is only useful for setting implicit targets. It expects a closure as the definition of the binding value

    bean(bean2, prop2: bind{ bean1.prop1 })
